Preparation stage

1. First, press the combination button (the combination button of each Android terminal is different, for example, some of them press and hold the Home key + volume down key continuously and then turn on, lasting for more than 3s),
   Enter fastboot mode. You can also use the ADB reboot bootloader command to enter the fastboot mode.
2. Connect USB to Android device to ensure fastboot devices can find Android device
3. The fastboot flash *.img command can be used to write various specified packages,
4. You can exit the fastboot mode and restart the system through fastboot reboot
5. Note 1: the following script's img file brush order cannot be changed at will.
6. Note 2: the img files written by each Android terminal are different. Please consult the corresponding R & D personnel or spm.
7. Note 3: there is a risk in brushing the machine. If it's not a professional R & D or testing personnel, please don't brush your Android device at will to avoid turning it into a brick!

Python batch script

Remember the essence of batch scripts: execute statements in batch order

#python3
#coding=utf-8

import os

print("Being fastboot Brush machine, Please wait a moment...")
os.system("fastboot oem format")
os.system("fastboot flash systemA system.img")
os.system("fastboot flash recoveryA recovery.img")
os.system("fastboot flash systemB system.img")
os.system("fastboot flash recoveryB recovery.img")
os.system("fastboot flash cache cache.img")
os.system("fastboot flash data data.img")
os.system("fastboot flash map map.img")
os.system("fastboot flash private private.img")
os.system("fastboot flash speech speech.img")
print("Brush machine finished, Restart...")
os.system("fastboot reboot")
os.system("pause")

Python procedure oriented functions

Process function oriented programming thinking should be as follows:
How many functions do you need to do this.
It's better to encapsulate all functions as well as possible. If you need to expose only some parameter interfaces, you can.
Package the previous script statement block, no need to pass parameters, and then call this FastBoot? Flash().

import os

def fastboot_flash():
    print("Being fastboot Brush machine, Please wait a moment...")
    os.system("fastboot oem format")
    os.system("fastboot flash systemA system.img")
    os.system("fastboot flash recoveryA recovery.img")
    os.system("fastboot flash systemB system.img")
    os.system("fastboot flash recoveryB recovery.img")
    os.system("fastboot flash cache cache.img")
    os.system("fastboot flash data data.img")
    os.system("fastboot flash map map.img")
    os.system("fastboot flash private private.img")
    os.system("fastboot flash speech speech.img")
    print("Brush machine finished, Restart...")
    os.system("fastboot reboot")

fastboot_flash()
os.system("pause")

Python object oriented classes

The programming thinking of object-oriented class should be as follows:
If you are given a blank world, what kinds of things do you need in this world,
What are the common attributes and methods of these kinds of things,
What is the relationship between these kinds of things (objects) and other kinds of things (objects).
Try to encapsulate these classes and only expose the external attributes (variables) and methods (functions).

import os

class FastbootFlasher():
    def __init__(self):
        pass

    def fastboot_flash(self):
        print("Being fastboot Brush machine, Please wait a moment...")
        os.system("fastboot oem format")
        os.system("fastboot flash systemA system.img")
        os.system("fastboot flash recoveryA recovery.img")
        os.system("fastboot flash systemB system.img")
        os.system("fastboot flash recoveryB recovery.img")
        os.system("fastboot flash cache cache.img")
        os.system("fastboot flash data data.img")
        os.system("fastboot flash map map.img")
        os.system("fastboot flash private private.img")
        os.system("fastboot flash speech speech.img")
        print("Brush machine finished, Restart...")
        
    def fastboot_reboot(self):
        os.system("fastboot reboot")

f_obj = FastbootFlasher()
f_obj.fastboot_flash()
f_obj.fastboot_reboot()
os.system("pause")

Operation mode

Make sure the Android device is connected to the computer through the USB cable, and successfully enters the fastboot mode,
fastboot device device is effectively connected,
Unzip the system version package, and then drop FastBoot? Flash.py to the unzipped folder,

Double click to run FastBoot? Flash.py.
